Problem
In several of the macros defined in TiBase.h, the log warnings about "expected: type, was: x" are backwards. They will show the actual type beside "expected" and the expected type beside "actual".

Error Message
When I tried to pass a label to a tab group's addTab method, I see the following. Note how expected and was are switched?
[ERROR] Invalid type passed to function. expected: TiUILabelProxy, was: TiUITabProxy in -[TiUITabGroupProxy addTab:] (TiUITabGroupProxy.m:65)
Reproduction
Drop the following in your app.js, and run it. The app will crash (as it should... we're adding a label to a tab group!) but you will notice the erroneous log message right before the nasty exceptions are thrown.
var tabs = Ti.UI.createTabGroup();
tabs.addTab(Ti.UI.createLabel());
tabs.open();

Confused: Why is an android test used to reopen an iOS bug?
Paras, since this is an iOS bug, we need to open a new bug for android (especially when the noted issue is fixed). So... please confirm this works on ios, and fi so close. AT that point, go ahead and log a new issue for android. Let Dustin or myself know if this is not clear. thanks!
App doesn't crash and error message is reported as expected.Hence closing the issue. Error message comes as Invalid type passed to function at app.js Log on the console [ERROR] Script Error { backtrace = "#0 () at :0"; line = 56; message = "Invalid type passed to function"; nativeLocation = "-[TiUITabGroupProxy addTab:] (TiUITabGroupProxy.m:78)"; nativeReason = "expected: TiUITabProxy, was: TiUILabelProxy"; sourceId = 303212608; sourceURL = "file://localhost/Users/global/Library/Application%20Support/iPhone%20Simulator/6.1/Applications/B4AB833B-8CB1-4070-A98A-CF7E91C45780/abc.app/app.js"; } Tested on: iOS version: 6 Studio : 3.0.2.201302041757 SDK version: 3.1.0.v20130325155928
